Nasal device



Patented Aug. 26, 1947 UNITED STATES PATENT OFFICE NASAL DEVICE v Joseph B. Biederman, Cincinnati, Ohio Application March 2, 1945, Serial No. 580,631

3 Glaims. (or. 128-148) This invention relates to improvements in a nasal device, that is, a device to be inserted Within the nostrils of a person suffering from respira tory disorders, such for example as hay fever.

Devices of the kind forming the subject matter of this invention are adapted to filter out pollens and other particles in the air and supply the air entering the users head with a medical Vapor. In the past, difiiculty has been encountered in the dislodgment of the device after being placed in the users nostril. At the same time these devices, while adjustable to difierent size nostril openings, were disturbed in normal use, requiring a readjustment of the parts. 337 the present in vention, the filtering devicesare definitely held against inadvertent maladjustment, and are prevented from displacement in the nostril.

It is the principal object of this invention to provide in a nasal device of the kind here disclosed, means for linking the filtering elements in the respective nostril openings to one another against independent rotation and dislodgment.

Another object of this invention is the provision of a removable device or link for accomplishing the foregoing object.

Another object of this invention is the provision of a removable member or link which not only prevents the dislodgment of the filtering device in each nostril, but secures each device in its individual adjustment to prevent maladjustment thereof after it has been arranged'to fit an individual users nostril opening.

Other objects and advantages of the present invention should be readily apparent by reference to the following specification considered in conjunction With the accompanying drawings forming a part thereof and it is to be understood that modifications may be made in the exact structural details there shown and described, within the scope of the appended claims, without de parting from or exceeding the spirit of the invention.

In the drawings:

Fig. 1 is a plan view of the device of this invention ready for use.

Fig. 2 is a transverse sectional view taken on line 22 on Fig. 1.

Fig. 3 is a, side elevation of one of the filtering devices.

Fig. 4 is an end elevation of the several elements forming the complete nasal filtering devlce.

Fig. 5 is a perspective View of the elements of one filtering assembly.

Throughout the several views of the drawings, similar reference characters are employed to de-' note the same or similar parts. The nasal'filtering device of this invention comprises threeseparate assemblies; the left nasal filter I0, the right nasal filter I I, and the connecting or bridging piece o link I2. The nasal filters l0 and II are each identical in construction, and it is deemed sufiicient if but one of them be described in detail.

The nasal filter It, see principally Fig. 5, comprises a pair of substantially U-shaped elements is and I l with said element I3 comprising arms I5 and I6 connected to one another by the rounded base I! whilethe element [4 has similar arms I8 and I9 connected to one anotherfby' the rounded base 20. The arm I5 of the element I3 is provided at its free ends with superimposed fingers 2! and 22 forming between them and the arm I5 a passageway. The arm [5 between the fingers 2| and '22, is provided with an inwardly projecting protuberance or lug 23. In addition, the element, I3 has projecting longitudinally thereof, from opposite sides of the base. I3, fingers 24 and 25,. and which fingers, see Fig. 2, lie between the arms I5 and IS. The arm I8 of the element I4 is provided longitudinally thereof With a, plurality of inwardly projecting sockets 26, which are adapted respectively to receive the protuberance 0r lug 23. In other words, the arm I8 is adapted to be inserted in the space provided below the fingers 2| and 22, wherefore the elements I3 and I4 telescope relative to one another and the various positions of adjustment is obtained by the interengagement of lug 23 with the sockets '26. This telescoping of the elements I3 and i4 causes the arm I B of element I3 to be exteriorly of the arm 19 of element I4, as illustrated clearly in Fig. l. The element I4, like element [3, has, projecting from opposite points of the rounded base 20, fingers 21 and 28.

The fingers M, 25, 21, and 28 cooperate with one another and with the bounding arms of the elements to hold a fibrous pad 29 which acts as a filter for the air drawn into the nostril by the user, and at the same time this pad may be saturated with a medicine picked up by the air as it passes therethrough for medicating the respiratory organs and the membranes thereof.

As was noted above, the filtering devices Ill and II are connected or linked together by link or bridging piece l2 which, see Fig. 4, is substantially U-shaped in elevation and comprises arms 30 and 3I joined by the base member 32. The lower ends of the arms 30 and El are flattened as at 33 and 34 providing shoulders 35 and 36 at the upper ends. The lower ends of the arms are turned on themselves to provide hooks 3! and 38.

The bridging piece is formed by resilient Wire, wherefore the hooks 3'! and 38 have yielding properties. In use and after the elements l3 and I4 of each filtering device It] and l l are properly adjusted, telescopically, the overlapped portions of arms l5 and I8 are inserted respectively in the hooks 3! and 38. The shoulders 35 and 36 are spaced from the hooks 31 and 38 a distance substantially equal to the height of the filter elements l3 and M, wherefore the lower edge of said elements engage the bottoms of the hooks while the upper edge of said elements engage the shoulders.

By this construction the clamping action of the hooks 31 and 38 adequately prevents inadvertent telescoping or extension of the elements M and 15 since it is necessary to remove the bridging piece l2 if any adjustment of these elements is necessary.

The bridging piece l2 at the same time prevents any rotative movement of either filtering device I 0 or i I, since movement of one will tend to carry with it a corresponding movement of the other, prohibited by the nostril, and therefore insuring the filterin device as a whole remaining in any position of adjustment.

What is claimed is:

1. In a nasal device the combination of a pair of nasal filter devices, a detachable U-shaped link for securing said filtering devices to one another in spaced apart relation, the free ends of the respective legs of said link being provided with resilient hooks adapted to engage over the edges of the respective filtering devices, and shoulders on said legs disposed to engage edges of said filtering devices opposite said hooks whereby said link is adjustable longitudinally of said filtering devices and said filtering devices are prevented from rotary movement with respect to' said link.

2. In a nasal device the combination of a pair of nasal filter devices, each of which comprises a pair of telescoping elements, 'a detachable U- shaped link for securing said filtering devices to one another in spaced apart relation, the free ends of the respective legs of said link being provided with resilient hooks adapted to engage over edges of the telescoping portions of the respective filter devices, and shoulders on said legs disposed to engage edges of the telescoping portions of said filter devices opposite said hooks, whereby said link is adjustable longitudinally of said filter devices and said filter devices are prevented from rotary movement with respect to said link,

3. In a nasal device the combination of a pair of nasal filter devices, each of which comprises a 'pair of telescopically adjustable half oval ele ments, one of the legs of one element of each pair being provided with a protuberance or lug, and one of the legs of the remaining element of each pair being provided with a plurality of means for engaging said protuberance or lug to secure the said elements in each pair in adjusted positions and a. detachable U-shaped link for securing the filter device in spaced apart relation, said link comprising hooks at the free ends of the respective legs of said link adapted to engage over edges of the telescoped legs of the respective elements, and shoulders on said legs disposed to engage over edges of the telescoped legs of the respective elements at points opposite to that engaged by the hooks.
